Back in the 50s - Need Venturi/Throttle Size for Teapots

I am looking for Primary & Secondary Venturi and Throttle Bore sizes for the Holley Teapots, the 2140 and also the 4000 carbs used 1953-1956 or so.

Of course a CFM rating at 1.5" Hg or any other number would be great too but that might be even more obscure.

My dad first brought me home a teapot to disassemble back in the mid-1960s, back then the cars that used them used to get wrecked Saturday nite at the Figure-8 races. Times sure change.

I've searched the web but cannot find these dimensions, any help??
